27th Jun 2023 | 8 | upends v

The vaping industry is in a state of constant evolution, with an extensive array of devices now available. This rapid expansion can be overwhelming for new vapers as they navigate through the various options and struggle to grasp the distinctions between them.

Sub-ohm vaping involves the use of a coil with a resistance below 1 ohm, often referred to as direct-to-lung (DTL) vaping. Contrasting with mouth-to-lung (MTL) devices, the technique for vaping with sub-ohm devices differs significantly. When using a sub-ohm device, envision taking a deep inhalation through your mouth, directly into your lungs, and exhaling immediately. These devices are specifically designed to generate substantial vapor clouds.

In this article, we are introducing one of the best sub-ohm vaping devices; Geekvape Z Sub-Ohm Tank.

What is Geekvape Z Sub-Ohm Tank?

Geekvape Z Sub-Ohm Tank is among the best MTL vaping tanks developed by Geekvape. It is characterized by a long and thin mouthpiece with an adjustable airflow control. With the tiny holes, Geekvape Z Sub-Ohm Tank assures you high precision when adjusting the airflow. Physically, Geekvape Z Sub-Ohm Tank has a "Z" letter that is unique to differentiate it from other counterfeit vape tanks in the market. The "Z" letter allows you to monitor the e-liquid level on the pod.

You can also know that you are using Geekvape Z Sub-Ohm Tank as it has a screwing part that you can use to attach it to the battery.

E-Liquid and E-Liquid Capacity

Geekvape Z Sub-Ohm Tank is engineered with an e-liquid pod with a capacity of 5ml. This capacity is enough to guarantee you up to 2500 puffs before it can be depleted and ready for refilling. Once the e-liquid is depleted, you can refill the tank with an e-liquid of your own flavor and nicotine strength.

Refilling the Geekvape Z Sub-Ohm Tank pod is simple and straightforward;

Unscrew the top cap - Grip the top cap of the Geekvape Z Sub-Ohm Tank firmly and twist it counterclockwise to unscrew it from the tank body.

Locate the filling ports - Once the top cap is removed, you will see two large filling ports on the top of the Geekvape Z Sub-Ohm Tank. These ports allow you to inject e-liquid into the tank.

Fill the tank - Hold your e-liquid bottle or dropper and carefully insert the nozzle into one of the filling ports. Slowly squeeze the bottle or release the dropper to add e-liquid into the tank. Be cautious not to overfill the tank, as this can cause leakage.

Replace the top cap - After filling the tank, fasten the top cap back onto the tank body by twisting it clockwise. Ensure it is tightened securely to prevent any leaks.

Allow the coil to saturate - Before vaping, it's crucial to give the coil time to saturate with the newly added e-liquid. Let the tank sit for a few minutes to allow the coil to absorb the liquid properly.

Adjust airflow (if necessary) - The Geekvape Z Sub-Ohm Tank features an adjustable airflow control ring. If desired, you can adjust the airflow by rotating the ring to increase or decrease the airflow according to your preference.

Design and Build Quality

Geekvape Z Sub-Ohm Tank features a design that is unique and gives you a unique vaping experience. Its physical machining gives a great physical look that you can admire on the first look. Its e-liquid tank is sturdy and built to allow you to monitor the e-liquid level without struggling through the "Z" clear window.

The design of the Geekvape Z Sub-Ohm Tank also takes care of the vaping coils. These coils are set to seat well and are easily locatable when you want to change them.

Geekvape Z Sub-Ohm Tank is further built to give you an option of 7 colors to choose from. You can choose Rainbow, Gunmetal, Black, Blue, Red, SS and also Red and Black. This means that you have the freedom to choose only the color that you like.

The Build quality of the Geekvape Z Sub-Ohm Tank is also acceptable. It is built to be leakproof, meaning that the e-liquid it accommodates does not leak in any way. The leakproof design is also advantageous as it prevents accidental leakages that could stain your clothing.

Adjustable Airflow

The Geekvape Z Sub-Ohm Tank features an adjustable airflow design, allowing you to customize the airflow to suit your vaping preferences. The adjustable airflow system consists of an airflow control ring situated at the base of the tank.

It utilizes a unique combination of direct top airflow and top-to-bottom airflow mechanisms. This innovative design allows for an impressive enhancement in both flavor and vapor production while ensuring reliable leakproof protection.

To adjust the airflow on the Geekvape Z Sub-Ohm Tank, follow these steps:

Locate the airflow control ring - Look for a ring at the base of the tank, just above the 510 connection. This ring has three airflow holes.

Rotate the airflow control ring - With your fingers, grip the airflow control ring and rotate it either clockwise or counterclockwise. This movement will open or close the airflow slots or holes, adjusting the amount of air that flows through the tank during inhalation.

Find your preferred airflow setting - Experiment with different airflow settings by gradually adjusting the airflow control ring. You can open it up for a more airy draw or close it down for a tighter, restricted draw. This allows you to customize your vaping experience, tailoring it to your personal preferences.

Different e-liquid flavors and coil resistances may perform better with specific airflow settings. So, feel free to explore and find the airflow configuration that provides the best flavor and vapor production for your particular setup.

Slide Coil Design

The Geekvape Z Sub-Ohm Tank features a convenient Quick Slide Coil design, which enables swift and hassle-free coil replacement. This design simplifies the process of changing coils, ensuring that vapers can continue enjoying their vaping experience without extensive downtime.

To replace a coil in the Geekvape Z Sub-Ohm Tank, follow these steps:

Empty the E-Liquid Tank - Before replacing the coil, ensure that the tank is empty of any remaining e-liquid. You can either vape until the tank is depleted or carefully pour out any remaining liquid.

Unscrew the Base - Hold the tank firmly and twist the base counterclockwise to detach it from the tank body. The base is the bottom section of the tank that holds the coil.

Remove the Old Coil - Once the base is removed, you will see the installed coil. Grip the coil firmly and pull it out from the base. Discard the old coil properly.

Prime the Cew Coil -  Take the new coil and apply a few drops of e-liquid directly onto the cotton-wicking material within the coil. This step helps saturate the coil and prevent dry hits during initial use.

Insert the New Coil - Insert the primed coil into the base of the tank, ensuring a snug fit. Make sure the coil is properly aligned and positioned within the base.

Screw the Base Back on - Once the new coil is securely in place, reattach the base to the tank body by twisting it clockwise. Ensure it is tightened properly to prevent any leakage.

Fill the Tank and Wait - After replacing the coil, fill the tank with your preferred e-liquid through the designated filling ports. Allow the tank to sit for a few minutes to let the new coil fully absorb the e-liquid.
